    Karol did a great job analyzing my data. He gave me explanations for each regression he did, and was thorough in his results. Also he was able to figure out what needed to be done with my data without my explaining it each step of the way. 5/5 would hire again :)

    Hi Karol,I have a project that might interest you.It is not a hard modeling task to undertake, but I am currently out of time and would appreciate your help on this.The task in question is modelling electricity spot prices in the UK market with a GARCH model, split into a deterministic and a sto. Since it is for academic purposes and is only a part of the model it doesn&quot;t need great sophistication, but model validation and some reasoning in choosing the model, as well as the appropriate charts would have to be produced.The task isn&quot;t particularly huge or demanding, but I would need it completed urgently (Monday evening would be the latest deadline).Let me know if you&quot;re interested and I can provide you with more details/data/academic articles on the subject.Thank you,Rok
